Researchers exposed aged mouse cells to 50 Hz magnetic fields (the same frequency as power lines) and found the exposure promoted cancer-like changes. However, when they treated the cells with metformin, a diabetes drug, it blocked these harmful effects by reducing inflammation pathways. This suggests power line frequency EMF may be particularly concerning for older adults.
